APPARATUS FOR FEEDING COAGULANTS TO LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 667,127, dated January 29, 1901.

Application filed April 30, 1900. Serial No. 15,022. (No model.)

To all whom, it may concern:

Be it known that 1', ANTHONY HARRIS, a subject of the Queen of Great Britain, residing at Hunters Quay, county of Argyle, Scotland, (whose full postal address is 73 Queen Victoria street, London, England,) have invented certain new and useful Improvements in Apparatus for Feeding or Distributing and Mixing Liquids, of which the following is a specification.

This invention relates to apparatus for dividing a feed of liquid into or distributing it in a number of feeds or streams of different volume or rates of feed in definite predetermined ratios and which is also adapted to produce a mixing and stirring of the liquid where required.

The invention is particularly useful in the purifying treatment of crude waters with reagents or chemical solutions in which the reagents or chemicals are required to be mixed with the water to be treated in a definite proportion.

The invention consists, essentially, of an arrangement of revoluble vessels adapted to receive the liquid to be fed or distributed, from which vessels the liquid is caused to flow in one or more jets approximately at a tangent into an annular trough which is stationary, whereby the revoluble vessel is set in rotation. The annular trough is divided into compartments of different capacities in the desired ratio according to the feeds into which the liquid is to be divided or distributed, which compartments receive the liquid from the jet or jets of the revolving vessel in proportion to the size of the compartments, as the jets take a longer time to pass over the larger compartments than over the smaller ones, and they are consequently feeding into the larger compartments for a longer period than into the smaller compartments in a given ratio. Suitable pipe connections take the divided feed from the respective compartments to the apparatus or places at which they are to be utilized.

The invention will now be described with reference to the accompanying drawings, in which- Figure 1 is a plan view of adistributer constructed for two unequal rates of feed; Fig. 2, a vertical section of the same, showing the apparatus feeding into a mixing vessel. Fig. 3 is a detail sectional View through a portion of the tank 13, showing the manner of constructing the partitions 19 19, and the manner of varying the amount of water or other liquid received between the same. Fig. 4 is a perspective view of the movable portion of one of the partitions of the tank 13.

Referring to the drawings, 3 is the pipe bringing a supply of the liquid into a revoluble vessel 12, preferably floating in a tank 13 and provided with elbow-shaped exit-pipes 14. The liquid flowing into the revoluble vessel 12 and escaping through the elbow-pipes 14E arrives in the annular trough formed in the tank 13 by an inner wall 18, which annular trough in the present instance is divided into two compartments by two vertical plates 19, placed close together, so that there is a small compartment formed between these plates and a larger or main compartment consisting of the remainder of the annular trough, as will be seen by referring to the plan shown in Fig. l. The proportion between the dimensions of these two compartments is made to suit the required ratio of feed by means of an adjustable partition forming a part of one of the plates 19. This partition 19 is cut down to about half the height of the other and the upper portion 19 is made movable, as seen in Fig. 3. The movable portion 19 will be seen to be formed with outer and inner walls 25 and 26, respectively, which are adapted to lie against the outer and inner walls of the tank 13. A floor 27 connects the walls 25 and 26 and is formed with a depending portion 28 at each of its ends. Depending portions 29 and 30 upon the walls 25 and 26 join the edges of the depending portions 28 28. These depending portions of the movable partition are adapted to overhang the upper edge of the reduced fixed portion of the partition 19, as illustrated in Fig. 3 of the drawings. The movable partition is also formed with a partition proper, 31, extending from the wall 25 to the wall 26. This structure will be clearly seen by reference to Fig. 4 of the drawings. In order to prevent the said movable partition from tipping out of its proper position, hooked supporting projections, as 32 and 33, are formed at the upper edges of the walls 25 and 26 and are adapted to be supported upon the upper edges of the tank 13 and its inner wall 18. It will be evident from this description and by reference to Figs. 3 and 4 of the drawings that the movable partition can be so moved as to vary the size of the inlet between the partitions 19 19 at their upper edges, and thus vary the amount of water received between the said partitions. The liquid escaping through the elbows 14 and impinging on the liquid in the annular trough tangentially or at an angle thereto causes the vessel 12 to revolve. It will be seen that a considerably-larger amount of the liquid is delivered by the elbow-pipes 14 into the main portion of the trough than is delivered between the plates 19, as the elbow-pipes pass very rapidly over this small chamber.

The liquid delivered in the desired proportions into the two compartments of the annular trough is carried off to the place at which it is to be utilized by means of a suitable pipe ,2 from the larger compartment and a suitable pipe 6 from. the smaller compartment formed between the plates 19. For instance, where the liquid to be treated is crude water for feeding steam-boilers and like purposes, which it is desired to treat with reagents or chemicals and otherwise purify it, the distributor may be conveniently mounted directly on the vessel a, in which the treatment is to take place, and the crude water to be treated be fed directly into the vessel by the pipe ,2 from the main compartment of the distributer, while the pipe 6 takes from the smaller compartment a correspondingly smaller feed of the crude water into a solution apparatus of any suitable construction, as at 21, (shown in Fig. 2,) in which it is charged with the reagents or chemicals with which the water in the vessel a is to be treated. The amount of crude water fed into the vessel a through the pipe 2 for treatment therefore exceeds in a given ratio the amount leaving the distributer through the small chamber 19 and pipe 6 to pass into the solution apparatus 21, from whence it returns in the form of a solution of chemicals or reagents and enters the treating vessel a by pipe h. The rotation of the distributing vessel 12 is also utilized to effect a mechanical stirring or mixing of the water in the vessel a by means of a vertical shaft 15, connected with said distributing vessel and passing through the fixed spindle 16, which is made hollow for the purpose, which shaft 15 carries a mechanical stirrer, such as the blades 17, which are thus rotated within the vessel a.

In Fig. 2 the pipes h and z, delivering the solution and the water to be treated, are shown in position to discharge on the blades receiving their motion from the water-distributer in the manner described, so that the solution and the crude water are thoroughly mixed in the vessel. In this apparatus the purified water rises within the vessel a, outside of a shielding cylindrical wall 20, and is taken off by pipe 2 and conveyed to the storage-tank or a suitable filtering apparatus.

I declare that what I claim is- 1. An apparatus for distributing or feeding liquids, comprising a revoluble distributing vessel, a trough around said vessel, means for delivering liquid from the distributing vessel approximately tangentially into the trough to impinge-on the liquid therein at an angle adapted to rotate the vessel, and partitions within the trough dividing it into separate compartments for each required feed, the respective capacities of the compartments be ing in the ratio of the rates of feed required from said compartments, and pipe connec tions from said compartments to convey the liquid where required, in combination, substantially asdescribed.
